    Hello Inkspace expert,
     

    I have some images which is having black background, inside which there is an icon.
    How to extract this icon from image background.

    Remove black Background & Group RED icon as image.

    I tried this :--
    go Path->Trace Bitmap
    Multiple scans->Colors - Scans 2 
    Update" to check and "Apply
    so go Object->Ungroup - select the black part and delete
    But not working

    Previously this way it worked. 

    Is this image any special ?

    Please suggest, How to do this task ?

     

    Regards,
    Dinesh

    I'd ensure the bitmap is also removed... it does not automatically get deleted.

    Just like you have done, but also select and delete the original image, which is behind the vector group.

    See this is the result.
    But red image is not separated from black background.

    I did not deleted the background image, just separated them, see the attached result.

    Ungroup. Check Status bar at the bottom of the Inkscape window for info about selection.

    You are welcome. Another option is tracing in black and color it after.
